LNCUBATOR ATTACHMENT.

Specification of Letters Patent.

Application filed October 4, 1917. Serial No. 194,751.

- erated from outside an incubator to shift the position of the thermometer to bring it into easy reading distance or to dispose it at the center of the incubator chamber without necessitating the opening of the incubator door thereby preventing all danger of spoiling the hatch by the admission of air currents.

Another object is to so mount a carrier of this character that all possibility of tilting thereof is avoided.

Another object is to so construct a carrier of this character that the simple turning of the knob will cause the thermometer carried thereby to appear or disappear at the will of the operator. 7

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a side elevation with parts broken out of an incubator showing this improved attachment applied and with the thermometer in position for reading,

Fig. 2 is a horizontal section taken on the line 2-2 of Fig.1, and

Fig. 3 is a vertical section taken on the line 33 of Fig. 1.

In the embodiment illustrated, an incubator 1 of ordinary construction is shown having the usual incubating chamber 2 and which is here shown provided with double doors 3, although obviously a single door may be employed if found desirable to do so. This incubator proper constitutes no part of this invention and hence will not be described in detail.

The thermometer carrier constituting the invention is mounted in the incubating chamber 2 and is movable transversely thereof on laterally spaced track rails 4: which extend from front to rear of the incubator as is shown clearly in Figs. '2 and 3 and are arranged at an oblique angle, preferably about 15 from the front toward the rear (see Fig. 2) tofacilitate the movement of the carrier thereon without binding. A

spacing block 4 carried by the inner face of top "3" of the incubator, spaces the rails a suitable distance from said top (see Fig. 3). The carrier proper 5 is mounted to slide on these rails a and as shown is composed of a single piece of wire bent to form arms 6 and 7 which have eyes 8 through which the track rails 4: pass and operate as guides for the carrier. A U-shaped member 9 connects the inner ends of the arms 6 and 7 extending at right angles therefrom as is shown clearly in Figs. 1 and 3 and supported on the cross bar 10 thereof is a thermometer ll'which may be of any suitable or desired construction and is here shown mounted on a base plate having a rolled top 12 which is pivotally engaged with the cross bar 10 of the U-shaped member 9 of the carrier. It will thus be seen that when this carrier is moved on the track rails that the thermometer depending therefrom will be brought toward or away from the front of the incubator so that it may be normally disposed at the center of the incubating chamber above the eggs, in which position it will be exposed to the greatest heat contained in the incubating The. arm 7 of the carrier has a depending loop 15 through which extends the end 16 of a carrier actuating lever 17. This lever 17 is shown in the form of a bell-crank fulcrumed on a screw 18 which depends from the top of the incubating chamber and the 1 other end of said lever which is bent to form a right'angularly disposed arm .17 passes through a loop 19 depending from a rod 20 which extends transversely of the incubating
